IMPROVEMENT IN TUBULAB. AXLE.

TO ALL WIIOM IT MY CQN CERN I Beit known that I, T. C. RICE, of'Woreester, in tbe'co'nnty of Worcester, and State of Massachusetts, have inventeda. new and improved Tubular Wagon-Axle; and I do hereby declare that the followingjs a full, clear,

kc and use the same, reference being Figure 1 represents one end of my improved tubular uXle.

Figure 2 is 'n cross-sectiontaken in the line a: z, iig. 1.

Figure 3 is n cross-section, ,taken-'inthe line y y, ig.'1. Figure 4 is n longitudinal section ofthe arm', showing how it is inserted inthe tube of the body'of the axle. Similar letters oirefei-enee indicate corresponding parts. l

This invention. 'elates toy improvements inytjhe construction oituhulnr uklesforikagons nnd.- other vehicles; and they consist; rst, in attaching shouldered ofsets en the nxle,vover` which to fasten the clips t hold the in inserting srnnller tubes in the ends of the to give requisite strength, as hereinafter fully described,

A. represents the body of theaxle, formed of iron gas-pipe or other suitable metal pipe.

-The tubeAis let into the bed B, undi's secured to it,

order to make thexnfast together, and prevent loosening and slipping of the barrel of the axle, I'brsze or otherwise attach square-shouldered offsets c to the axle, upon which offsets the clips are boltedyas shown in the drawings. l' l A V In order to form the arm C smnller and with proper taper, without weakeningit, anduvalso to increase the strength of the axlent and` near the inner end ,ofv the arm, I insert smaller tubes-of metal in the ends of the .tubular axle, and extending-into it beyond or inside-of the collar d, and upon the outerv tube, or upon both tubes, outside of the collar, I taper or shape the arm.

The smaller tube, to form the arm, isinsertedsjn the tubular asie as fur as necessary to give the requisite nited by brazing', screwing, shrinking together `withrecesses, or in any suitable manner to hold them fast together. A

Hnvin'g'thus described my invention, I claim as new, and desire to secure by LettersPatent- The square-shouldered offsets c c, on thejaxle A, for' securing it to the wooden bed B. with the clips a a, which jt over such shoulder, as herein shown end described.
